Drying chamber for raw cement to Qatar

12-11-2014

Estanda has supplied the cement Group QATAR NATIONAL CEMENT Co.optimized designs for the drying chamber for the raw cement grinding process.

The aim of this project is to improve the drying chamber performance as the previous designs for pieces in laminated steel showed high levels of wear, causing installation delays, production losses, and high maintenance costs. The drying chambers were installed on line 4 of the nº1 and 2 horizontal ball mills, which the Group has in Doha.

Inlet headwalls liners and liners made of wear and temperature resistant (400ºC) steel with a chromium (Cr) content of approximately to 10% were supplied.

This project has successfully improved production and has notably reduced maintenance costs.
